pm_os::isLinux Interface Reference

Generate and return .true. if the runtime operating system is Linux. More...

Detailed Description

Generate and return .true. if the runtime operating system is Linux.

The identification of an operating system as Linux requires either:

1. the ParaMonte library to have been compiled with the FPP macro LINUX_ENABLED=1, or,
2. the value returned by the runtime shell command uname -o match or contain the keyword linux.

Parameters

[out]	failed	: The output scalar logical of default kind LK that is .true. if and only if an error occurs while inferring the operating system type. (optional. If missing and a runtime error occurs, the program will halt by calling error stop.)
[in,out]	errmsg	: The input/output scalar character of default kind SK of arbitrary length type parameter. If an error occurs, errmsg will be set to a descriptive message about the nature of the runtime error. A length of LEN_IOMSG characters is likely sufficient to capture most error messages in full. (optional. If missing, no error message will be output. Its presence is relevant only if failed is also present.)

Returns

itis : The output scalar logical of default kind LK that is .true. if and only if the runtime operating system is Linux, otherwise, .false..

Possible calling interfaces ⛓

use pm_os, only: isLinux
use pm_kind, only: LK
logical(LK) :: failed
logical(LK) :: itis
character(255, SK) :: errmsg = SK_""
 
itis = isLinux()
itis = isLinux(failed)
itis = isLinux(failed, errmsg)

Remarks

The procedures under discussion are impure.

program example
 
    use pm_kind, only: LK, IK, SK
    use pm_os, only: isDarwin, isLinux, isWindows

    call disp%show( [isDarwin(), isLinux(), isWindows()] )
    call disp%skip()
 
    call disp%skip()
    call disp%show("if (sum(getInt([isDarwin(), isLinux(), isWindows()])) /= 1) error stop 'Multiple Operating Systems cannot exist simultaneously at runtime!'")
                    if (sum(getInt([isDarwin(), isLinux(), isWindows()])) /= 1) error stop 'Multiple Operating Systems cannot exist simultaneously at runtime!'
    call disp%skip()
